The rotor’s 25.8 mm nominal thickness and 24.4 mm discard thickness provide the key wear measurements used during brake inspection, while the 14.9 mm stud\/lug hole diameter and 120 mm bolt circle support correct wheel mounting geometry. For BMW 135i front right applications, BMW 135is front right applications, and select BMW 328i and 330i front right retrofit configurations, this rotor is built to align with the original brake package requirements noted in the fitment data.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Rotor Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation from a worn or uneven front rotor surface\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency caused by rotor wear beyond discard thickness\u003c\/li\u003e\n\u003cli\u003eCorrosion on the rotor hat area\u003c\/li\u003e\n\u003cli\u003eBrake noise associated with a damaged or heat-affected rotor face\u003c\/li\u003e\n\u003cli\u003eFitment issues when replacing the front right rotor on listed BMW models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify rotor dimensions, bolt pattern, and front right position before installation. Confirm whether the vehicle uses the standard rotor setup, optional full cast rotor design, or original design aluminum hat front rotor configuration listed in the fitment notes for BMW 135i, BMW 135is, BMW 328i, and BMW 330i. Because this rotor uses a directional brake surface, install it in the correct orientation for the front right side.\u003c\/p\u003e\u003cp\u003eFits 2008-2013 BMW 135i, front right.
